Porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) are a class of crystalline framework materials that are constructed from the coordination bonds of metal ions/clusters and organic linkers. Since their discovery of being porous, PCPs have been thoroughly investigated as promising adsorptive materials. Among them, structurally responsive PCPs, or flexible PCPs, often exhibit fascinating structural properties because they can have different interconvertible structures depending on external parameters. [1-2]
However, developing artificial porous systems that exhibit high molecular recognition performance is still a significant challenge. Achieving selective uptake of a specific component from a mixture of many similar species, regardless of their size and affinity, is a difficult task. Therefore, a porous platform that integrates multiple recognition mechanisms working cooperatively for highly efficient guest identification is desired. [3-4]
To address this challenge, we designed a flexible porous coordination polymer (PCP) that features a corrugated channel system. This system cooperatively responds only to target gas molecules by taking advantage of its stereochemical shape, location of binding sites, and structural softness. Compared to known molecule recognition strategies, including molecular sieving and functional interacting sites, the proposed intelligent host-responsive molecular recognition mechanism based on the narrow-corrugated channel structure brings unprecedented recognition efficiency. This study successfully demonstrates that unique molecule recognition performance can be achieved through the deliberate organization of pore geometry, structure softness, and binding sites at the molecular-level precision in a defined molecular structure.
In this symposium, the details of the syntheses, crystal structures, in situ X-ray investigations, as well as theoretical studies on the mechanism of exclusive sorption behaviors are discussed.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
